I just found (but haven't used yet) instructions from the Armbian forums, which include how to install to eMMC
https://docs.armbian.com/User-Guide_Getting-Started/
Using Armbian-config brings up the message on the Tritium ALL-H3-CC of no available target. This despite the fact that the eMMC is installed and working. I know this because if I remove the SDC, from which the unit is operating and then cold boot the unit, I boot into the 'DragonBoard' environment installed on the eMMC now.
Have other solutions to this been found?
hmm, no target for me either
The eMMC bindings are not in the device tree in mainline so it has to be added manually. Please create a ticket in the Armbian forum about this.
wow! Do you know those manual changes?
Or even better just use this: https://github.com/zador-blood-stained/fel-mass-storage
Yeah... about that. Tried following those instructions on a Debian laptop. Can't get sunxi-fel to build properly. Keeps returning a fatal error for the missing 'libusb.h' include, which I have confirmed over and again is present. Tried various adds to the $PATH variable with no luck.
I put libusb.h in the sunxi-tools/include folder I get a string of errors two pages long with missing usb libraries.
So at this point, unless somebody comes up with another way to do it, typical users, like myself, are unable to access the eMMC or write a bootable image to it. :-(

Some information from https://github.com/zador-blood-stained/fel-mass-storage is erroneous, or omitted...
The following assumes you have followed the instructions to clone the sunxi-tools to your home directory and that you have installed the libusb-1.0-dev.
sudo cp /user/include/libusb-1.0/libusb.h ~/sunxi-tools/includesudo apt-get updatesudo apt-get install pkg-configsudo make sunxi-felBingo! sunxi-fel is compiled!
sudo ./sunxi-fel versionIf connection has failed the command will return the line...
ERROR: Allwinner USB FEL device not found!If connection is successful the command will return something similar to...
AWUSBFEX soc=00001718(H5) 00000001 ver=0001 44 08 scratchpad=00017e00Next up... burning a bootable armbian image to the device!
@DWheaton55 Thanks for the write-up. Only one of the ports is the OTG port so only the USB port you mentioned will work. Official images are coming soon as well. Waiting for Linux 4.18 to stabilize.
There is still a problem, at least one I have yet to resolve. That is that once the Tritium is recognized by Sunxi-fel it remains invisible as a USB, or other storage device to the Debian OS. So I am still unable to write an image to the eMMC.
This is a significant revision to my earlier post from June 28, 2018.
The instructions to make the sunxi-tools remain relevant, but the method for accessing the Tritium in 'FEL' mode are much easier.
Go back to the original site, https://github.com/zador-blood-stained/fel-mass-storage
From there download the fel-sdboot.img 2MB file to the desktop of the host computer and then use a tool like Etcher to flash the fel-sdboot.img file to an SD Card.
Unplug the Tritium unit from your host computer's USB port. Then insert the SD Card into your Tritium device. Plug the Tritium unit back to the host computer's USB port without pressing the UBOOT button. The red LED should light and remain solid with no blinking blue or green LED.
From the CLI on the host computer run the sunxi-fel command from the root of the sunxi-tools directory.
sudo ./sunxi-fel --list --verboseThe connection should be successful as shown above. To further test the connection complete the 'Preparations' section of the instructions to add the UDEV rule. Once that is done reboot the host computer to reload all UDEV rules, including the newly added rule.
Note: Unplug the Tritium prior to rebooting and then plug it back in after reboot is complete.
After reboot run the following command:
lsusbThe Tritium device with eMMC in flashing mode should show a line similar to:
Bus 00n Device 00n: ID 1f3a:efe8 Onda (unverified) V972 tablet in flashing modeI have concluded that Sunxi-tools, as used in this thread, will allow the eMMC to be seen by the Armbian build, but not mounted.
Other posts on the Libre Computer web site, including the eMMC Flashing Guide, make reference to Linux images that are not yet available for the Tritium. The source files for Libre's "lc_distro_transfer" utility are also not available to build for access to the Tritium's onboard eMMC.
As of now, there is no solution to porting the OS to the eMMC for booting until Libre provides it.
Agreed Nkfs. The fel-mass-storage information on Github "might" work with an H3 board with eMMC, but I have definitively ruled out any possibility of it working with the H5 SoC.
I have also joined the Libre Computer FaceBook page and there is no information there about this issue that is useful in resolving the problem.
The instructions provided for LePotato, which are referred to as a possible solution somewhere else in this forum are a dead end as well. None of the builds available for that platform will boot on the H5 board I have, meaning further implementation of those instructions are equally useless.
I'm still at the point I was when I posted on July 5th that Libre Computer must provide support in resolving the eMMC issue. Until then the Tritium sits on the bench with nothing to do but wait!
So here we are nearly midway through September 2018 and I think everyone who ordered an eMMC with their Tritium boards (H3 or H5) are in the same boat; no way to access the device or make it a useful part of that system.
When might we expect Libre Computer to resolve this issue?
@Nkfs wait a few hours
So does the eMMC not get detected correctly on these boards? I was going to order one and noticed in the US, it's not being sold over at Amazon. I was curious as to why and then found this in the forum. Guess I shouldn't be ordering one of these, hey?
The 4.x eMMC modules will be available in the US in approximately two weeks.
Great! Thanks for letting me know.
